Description
Technical Field
[0001] The utility model belongs to the technical field of bicycle protection, and particularly relates to a reusable corrugated paper disc brake protection cover. Background Art
[0002] The bicycle disc brake is a key component of the disc brake system. It consists of a brake disc connected to the wheel and a brake caliper on the edge of the disc. When the rider selects the brake, the high-pressure brake fluid pushes the brake pads to clamp the brake disc, thus producing a good braking effect.
[0003] At present, bicycle disc brakes generally need to adopt a protective structure during transportation after production and processing. In the prior art, a protective structure made of plastic material is usually used for covering and protecting. The use of plastic material for protection has certain defects and shortcomings during its use. During its use, the plastic material is harmful to the environment whether it is during production or discarded in the external environment. It can be seen that its environmental performance during use is not good, so it needs to be improved. Utility Model Content
[0004] In view of the problems mentioned in the background technology, the purpose of the utility model is to provide a reusable corrugated paper disc brake disc protective cover to solve the problems raised by the background technology.
[0005] The above technical objectives of the utility model are achieved through the following technical solutions:
[0006] A reusable corrugated paper disc brake disc protective cover comprises a corrugated paperboard, both sides of the corrugated paperboard are provided with limiting grooves, both sides of the corrugated paperboard are rotatably connected with sub-plates, the inner side of the sub-plate is fixedly installed with a limiting paperboard, the limiting paperboard is slidably connected to the inner side of the limiting groove, a buffer is fixedly installed in the middle of one side of the corrugated paperboard, the corrugated paperboard, the sub-plate and the limiting paperboard are all composed of composite paperboard, and the protective cover mainly consists of the corrugated paperboard, the sub-plate, the limiting paperboard and the buffer. The corrugated cardboard is provided with limit grooves on both sides to facilitate the insertion and fixation of the brake disc. The sub-plate is rotatably connected to the corrugated cardboard, and limit cardboards are provided on the inside. These limit cardboards can slide into the limit grooves to ensure that the brake disc is firmly clamped. The corrugated cardboard, sub-plate and limit cardboard are all made of composite cardboard, which is light and has certain strength and toughness, and can meet the needs of packaging and protection. Through the clamping limit design, the protective cover can be easily installed and removed, so that the corrugated cardboard can be used multiple times, which is in line with the principles of environmental protection and economy. A buffer is installed in the middle of one side of the corrugated cardboard, and the buffer includes a buffer spring and a buffer plate. This design can effectively absorb external shocks and vibrations and protect the brake disc from damage during transportation.
[0007] As a preferred technical solution, the buffer component includes a buffer spring, which is fixedly connected to the middle part of one side of the corrugated cardboard. A buffer plate is fixedly installed on the outer end of the buffer spring. The buffer component is mainly composed of a buffer spring and a buffer plate. The buffer spring is fixedly connected to the middle part of one side of the corrugated cardboard, which enables the spring to firmly support and protect this side of the brake disc. When subjected to external impact, the buffer spring can deform, absorb and disperse the impact force, thereby preventing the impact force from directly acting on the brake disc. The buffer plate is fixedly installed on the outer end of the buffer spring. The buffer plate not only enhances the stability and overall structural strength of the buffer component, but also can directly contact the brake disc to provide it with additional support and protection.
[0008] As a preferred technical solution, firstly, the existence of the U-shaped reserved groove provides additional support and fixing space for the brake disc. When the brake disc is placed inside the protective cover, part of its structure can be embedded in the reserved groove, which can ensure that the brake disc remains stable during transportation and is not prone to shaking or shifting. Secondly, the design of the U-shaped reserved groove also takes into account the shape and size of the brake disc. By setting the shape of the reserved groove to a U-shape that matches the brake disc, it can better adapt to the contour of the brake disc and provide a closer support. This design not only enhances the stability of the protective cover, but also effectively prevents the brake disc from being subjected to unnecessary pressure and friction inside the package. In addition, the U-shaped reserved groove also has a certain degree of elasticity and can adapt to brake discs of different sizes and shapes. This flexibility enables the protective cover to be suitable for a wider variety of brake discs, improving its versatility and practicality.
[0009] As a preferred technical solution, pillars are fixedly installed at equal intervals on the outer surface of the corrugated cardboard, and the pillars are configured as corrugated paper columns. Pillars are fixedly installed at equal intervals on the outer surface of the corrugated cardboard, and these pillars are designed as corrugated paper columns. This design brings advantages in many aspects. First, the addition of corrugated paper columns enhances the overall structural strength and stability of the corrugated cardboard. The pillars serve as additional support points, which can effectively prevent the cardboard from deformation or damage when subjected to external forces, thereby ensuring that the brake disc is better protected during the packaging process.
[0010] As a preferred technical solution, the composite paperboard includes a paper substrate, which is arranged inside the corrugated paper, and the outer side of the paper substrate is fixedly connected with a flame retardant coating, the outer side of the flame retardant coating is bonded with a wear-resistant layer, and the outer side of the wear-resistant layer is coated with a wear-resistant coating. The paper substrate serves as the base layer of the composite paperboard and provides basic support and strength for the entire structure. It is located inside the corrugated paper to ensure the overall stability and durability of the paperboard. Secondly, the flame retardant coating is fixed on the outer side of the paper substrate. The main function of this flame retardant coating is to enhance the flame retardant properties of the paperboard, so that it can slow down the burning speed or prevent the occurrence of burning when encountering a fire source, thereby protecting the brake disc and other items from fire damage. Then, on the outer side of the flame retardant coating, the wear-resistant layer is fixed by bonding. The wear-resistant layer is usually made of a material with excellent wear resistance, which can effectively resist external friction and scratching and extend the service life of the protective cover. Finally, a wear-resistant coating is coated on the outer side of the wear-resistant layer, and this wear-resistant coating further enhances the wear resistance of the paperboard.
[0011] As a preferred technical solution, the paper substrate is set to be a kraft paper substrate, and the flame retardant coating is set to be a phosphorus-containing flame retardant coating. First, the kraft paper substrate, as a high-strength and high-toughness paper material, provides excellent support and stability for the composite paperboard, and its excellent mechanical properties ensure that the corrugated paper disc brake disc protective cover can maintain its shape and structural integrity during transportation and storage, and effectively prevent the brake disc from being squeezed or deformed. Secondly, the phosphorus-containing flame retardant coating is used as a flame retardant coating to provide the composite paperboard with excellent flame retardant properties. The phosphorus-containing flame retardant can quickly form a stable carbonized layer when heated, isolating oxygen and flames, thereby effectively delaying or preventing combustion. This feature enables the corrugated paper disc brake disc protective cover to play an excellent protective role in the face of unexpected situations such as fire.
[0012] As a preferred technical solution, the wear-resistant layer is set as a wear-resistant paper layer, and the wear-resistant coating is set as a molybdenum disulfide coating. The wear-resistant paper layer as a wear-resistant layer itself has excellent wear-resistant properties. It can effectively resist external friction and scratches and protect the internal paper substrate from damage. This material usually has high hardness and toughness and can maintain good wear resistance during long-term use. The molybdenum disulfide coating as a wear-resistant coating further enhances the wear resistance of the composite paperboard. Molybdenum disulfide is an excellent solid lubricant with a low friction coefficient and good lubricating properties. It can be coated on the outside of the wear-resistant paper layer to form a lubricating film, which reduces the friction between the brake disc and the protective cover and reduces wear.
[0013] In summary, the utility model mainly has the following beneficial effects:
[0014] First, by setting the limit grooves on the corrugated paperboard and the sub-board, the brake disc can be easily covered and quickly disassembled and reused. Corrugated paper comes from renewable resources, is environmentally friendly and easy to degrade. Compared with plastic, it has less burden on the environment and is more economical, which helps to reduce production costs. Corrugated paper also has excellent buffering performance, which can effectively protect the brake disc from damage and ensure the integrity of the product. Its lightness and easy handling make the packaging process more convenient. In addition, the plasticity and printing performance of corrugated paper also enable it to meet the packaging needs of brake discs of different specifications and improve the aesthetics and market competitiveness of the product.
[0015] Second, the kraft paper substrate has high mechanical strength and stability, can withstand a certain amount of pressure and tension, and maintain the integrity of the structure. The phosphorus-containing flame retardant coating can play an effective flame retardant role when the material burns, reducing the risk of fire. The phosphorus-based flame retardant only produces non-toxic and harmless phosphorus compounds when burning, and will not cause pollution to the environment. The wear-resistant paper layer can significantly increase the wear resistance of the composite material and extend its service life. The wear-resistant paper layer can effectively prevent the substrate from being scratched and worn, maintaining the appearance and performance of the material. The molybdenum disulfide coating has excellent lubrication properties, which can reduce the friction coefficient between materials and reduce wear. At the same time, it has a certain corrosion resistance and can resist the erosion of some chemical substances. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0021] Example
[0022] refer to Figures 1 to 4The embodiment of the present invention discloses a reusable corrugated paper disc brake disc protective cover, comprising a corrugated paperboard 1, both sides of which are provided with limiting grooves 2, both sides of which are rotatably connected with sub-plates 3, the inner side of which is fixedly provided with limiting paperboards 4, which are slidably connected to the inner side of the limiting grooves 2, a buffer 6 is fixedly provided at the middle of one side of the corrugated paperboard 1, the corrugated paperboard 1, the sub-plate 3 and the limiting paperboard 4 are all composed of composite paperboards 7, and the protective cover mainly consists of the corrugated paperboard 1, the sub-plate 3, the limiting paperboard 4 and the buffer 6. Limiting grooves 2 are provided on both sides of the corrugated paperboard 1 to facilitate the insertion and fixation of the brake disc. The sub-plate 3 is rotatably connected to the corrugated cardboard 1, and a limiting cardboard 4 is provided on the inner side. These limiting cardboards 4 can slide into the limiting groove 2 to ensure that the brake disc is firmly clamped. The corrugated cardboard 1, the sub-plate 3 and the limiting cardboard 4 are all composed of composite cardboard 7. This material is both light and has a certain strength and toughness, which can meet the needs of packaging and protection. Through the clamping limiting design, the protective cover can be easily installed and disassembled, so that the corrugated cardboard 1 can be used multiple times, which is in line with the principles of environmental protection and economy. A buffer 6 is installed in the middle of one side of the corrugated cardboard 1, and the buffer 6 includes a buffer spring 61 and a buffer plate 62. This design can effectively absorb external shocks and vibrations and protect the brake disc from damage during transportation.
[0023] refer to Figure 1-Figure 2The buffer member 6 includes a buffer spring 61, which is fixedly connected to the middle part of one side of the corrugated cardboard 1. A buffer plate 62 is fixedly installed on the outer end of the buffer spring 61. The buffer member 6 is mainly composed of a buffer spring 61 and a buffer plate 62. The buffer spring 61 is fixedly connected to the middle part of one side of the corrugated cardboard 1, which enables the spring to firmly support and protect this side of the brake disc. When subjected to external impact, the buffer spring 61 can deform, absorb and disperse the impact force, thereby preventing the impact force from directly acting on the brake disc. The buffer plate 62 is fixedly installed on the outer end of the buffer spring 61. The buffer plate 62 not only enhances the stability and overall structural strength of the buffer member 6, but also directly contacts the brake disc to provide it with additional support and protection. At the same time, the buffer plate 62 can further disperse and absorb the impact force, further reducing the risk of damage to the brake disc. First of all, The existence of the U-shaped reserved groove 63 provides additional support and fixing space for the brake disc. When the brake disc is placed inside the protective cover, part of its structure can be embedded in the reserved groove 63, which can ensure that the brake disc remains stable during transportation and is not prone to shaking or shifting. Secondly, the design of the U-shaped reserved groove 63 also takes into account the shape and size of the brake disc. By setting the shape of the reserved groove 63 to a U-shape that matches the brake disc, it can better adapt to the contour of the brake disc and provide a more fitting support. This design not only enhances the stability of the protective cover, but also effectively prevents the brake disc from being subjected to unnecessary pressure and friction inside the package. In addition, the U-shaped reserved groove 63 also has a certain degree of elasticity and can adapt to brake discs of different sizes and shapes. This flexibility enables the protective cover to be suitable for more types of brake discs, thereby improving its versatility and practicality.
[0024] refer to Figure 1-Figure 2 The outer surface of the corrugated cardboard 1 is fixedly installed with pillars 5 at equal intervals, and the pillars 5 are set as corrugated paper columns. The outer surface of the corrugated cardboard 1 is fixedly installed with pillars 5 at equal intervals, and these pillars 5 are designed as corrugated paper columns. This design brings advantages in many aspects. First, the addition of corrugated paper columns enhances the overall structural strength and stability of the corrugated cardboard 1. The pillars 5, as additional supporting points, can effectively prevent the cardboard from being deformed or damaged when subjected to external forces, thereby ensuring that the brake disc is better protected during the packaging process. Secondly, the equidistant design makes the pillars 5 on the corrugated cardboard 1 evenly distributed, which not only improves the overall bearing capacity of the cardboard, but also ensures that the brake disc is evenly supported inside the package, which helps to reduce the potential risk of damage caused by uneven force. In addition, using corrugated paper columns as the material of the pillars 5 not only maintains the environmental protection of the material, but also makes the pillars 5 and the corrugated cardboard 1 have good compatibility and synergy. The manufacturing process of the corrugated paper columns is relatively simple and the cost is low, which further improves the economy of the entire protective cover.
[0025] refer to Figure 1-Figure 2The composite paperboard 7 includes a paper substrate 71, which is arranged inside the corrugated paper. A flame retardant coating 72 is fixedly connected to the outside of the paper substrate 71. A wear-resistant layer 73 is bonded to the outside of the flame retardant coating 72. The outside of the wear-resistant layer 73 is coated with a wear-resistant coating 74. The paper substrate 71, as the base layer of the composite paperboard 7, provides basic support and strength for the entire structure. It is located inside the corrugated paper to ensure the overall stability and durability of the paperboard. Secondly, the flame retardant coating 72 is fixed on the outside of the paper substrate 71. The main function of this flame retardant coating 72 is to enhance the flame retardant performance of the paperboard, so that it can slow down the burning speed or prevent the occurrence of burning when encountering a fire source, thereby protecting the brake disc and other items from damage by fire. Then, the flame retardant coating 74 is coated on the outside of the paper substrate 71. The outer side of the layer 72 is fixed with a wear-resistant layer 73 by bonding. The wear-resistant layer 73 is usually made of a material with excellent wear resistance, which can effectively resist external friction and scratches and extend the service life of the protective cover. Finally, a wear-resistant coating 74 is coated on the outer side of the wear-resistant layer 73. This wear-resistant coating 74 further enhances the wear resistance of the paperboard, so that it can still maintain a good appearance and performance when facing frequent friction and wear. Through such a multi-layer structure design, the composite paperboard 7 not only has good support and strength, but also has multiple properties such as flame retardancy and wear resistance, thereby greatly improving the overall protection effect and service life of the corrugated paper disc brake protective cover. At the same time, this design also fully considers environmental protection and economy, and meets the current green and sustainable development needs.
[0026] refer to Figure 1-Figure 4 , the paper substrate 71 is set as a kraft paper substrate, and the flame retardant coating 72 is set as a phosphorus-containing flame retardant coating. First, the kraft paper substrate, as a high-strength and high-toughness paper material, provides excellent support and stability for the composite paperboard 7. Its excellent mechanical properties ensure that the corrugated paper disc brake disc protective cover can maintain its shape and structure integrity during transportation and storage, and effectively prevent the brake disc from being squeezed or deformed. Secondly, the phosphorus-containing flame retardant coating as the flame retardant coating 72 provides excellent flame retardant performance for the composite paperboard 7. The phosphorus-containing flame retardant can quickly form a stable carbonization layer when heated, isolating oxygen and flames, thereby effectively delaying or preventing combustion. This characteristic enables the corrugated paper disc brake disc protective cover to play an excellent protective role in the face of unexpected situations such as fire, ensuring the safety of the brake disc and other items. In addition, the phosphorus-containing flame retardant also has the characteristics of low smoke and non-toxicity. Less smoke and toxic gases are generated during the combustion process, which is beneficial to protecting the safety of personnel. At the same time, the phosphorus-based flame retardant also has good water resistance and moisture resistance, so that the composite paperboard 7 can still maintain stable performance in a humid environment.
[0027] refer to Figure 1-Figure 4The wear-resistant layer 73 is set as a wear-resistant paper layer, and the wear-resistant coating 74 is set as a molybdenum disulfide coating. The wear-resistant paper layer as the wear-resistant layer 73 itself has excellent wear-resistant properties. It can effectively resist external friction and scratches and protect the internal paper substrate 71 from damage. This material usually has high hardness and toughness and can maintain good wear resistance during long-term use. The molybdenum disulfide coating as the wear-resistant coating 74 further enhances the wear resistance of the composite paperboard 7. Molybdenum disulfide is an excellent solid lubricant with a low friction coefficient and good lubrication performance. It can be coated on the outside of the wear-resistant paper layer to form a lubricating film, reduce the friction between the brake disc and the protective cover, and reduce wear. At the same time, the molybdenum disulfide coating also has excellent high temperature resistance and can maintain a stable lubrication effect under high temperature environment to ensure the safety of the brake disc during transportation and storage. In addition, the molybdenum disulfide coating also has good adhesion and anti-corrosion properties, and can be tightly attached to the wear-resistant paper layer to form a solid protective layer to prevent the invasion of external moisture and corrosive substances and extend the service life of the protective cover.
[0028] Principle and advantages of use: By setting the corrugated cardboard 1 and the limiting groove 2 on the auxiliary plate 3, the two ends of the brake disc are inserted into the inner part of the limiting groove 2, the auxiliary plate 3 is turned over to make the limiting plate fit the outer surface of the brake disc in the opposite direction, and the auxiliary plate 3, the limiting plate and the brake disc are contacted and limited, so that the device can be set to cover the outer surface of the brake disc. At this time, the corrugated cardboard 1 can fit the outer surface of the brake disc, which can play a good protective performance. In addition, it adopts a card-connected limiting design, and the corrugated cardboard 1 can be quickly disassembled and assembled during use, which is convenient for reuse. Corrugated paper comes from renewable resources, such as wood, and the environmental pollution generated during its production and treatment is relatively small. Compared with plastic, corrugated paper is easier to degrade after being discarded, and has a smaller burden on the environment. It conforms to the current trend of green and environmentally friendly packaging. The price of corrugated paper is usually more economical than plastic. Using corrugated paper as packaging material can reduce production costs and improve the economic benefits of enterprises. Corrugated paper has good buffering properties and can effectively absorb external shocks and vibrations. During transportation, this helps protect the bicycle brake disc from damage or deformation, ensuring the integrity and safety of the product. Corrugated paper packaging materials are usually lightweight and easy to carry and store. In addition, corrugated paper has strong plasticity and is easy to process into various shapes and sizes to meet the packaging needs of bicycle brake discs of different specifications and models. Corrugated paper has good printing properties and can be printed with various patterns and texts to enhance the aesthetics and brand image of the product. At the same time, through packaging design, it can attract consumers' attention and improve the market competitiveness of the product.
[0029] The kraft paper substrate has high mechanical strength and stability, can withstand a certain amount of pressure and tension, and maintain the integrity of the structure. The phosphorus-containing flame retardant coating can play an effective flame retardant role when the material burns, reducing the risk of fire. The phosphorus-based flame retardant only produces non-toxic and harmless phosphorus compounds when burning, and will not cause pollution to the environment. The wear-resistant paper layer can significantly increase the wear resistance of the composite material and extend its service life. The wear-resistant paper layer can effectively prevent the substrate from being scratched and worn, maintaining the appearance and performance of the material. The molybdenum disulfide coating has excellent lubrication properties, which can reduce the friction coefficient between materials and reduce wear. At the same time, it has a certain corrosion resistance and can resist the erosion of some chemicals.
